We describe a screen for cellular response to drugs that makes use of haploid embryonic stem cells. We generated ten libraries of mutants with piggyBac gene trap transposon integrations, totalling approximately 100,000 mutant clones. Random barcode sequences were inserted into the transposon vector to allow the number of cells bearing each insertion to be(More)
Human DNA Topoisomerase I is a 765aa monomeric enzyme composed of four domains: the N-terminal domain, highly charged and responsible for several protein-protein interactions, the core domain that embraces the DNA during catalysis, the highly charged linker domain and the C-teminal domain containing the active site. The enzyme promotes the relaxation of(More)
Excision repair cross-complementation group 1 (ERCC1) is a DNA repair enzyme that is frequently defective in non-small cell lung cancer (NSCLC). Although low ERCC1 expression correlates with platinum sensitivity, the clinical effectiveness of platinum therapy is limited, highlighting the need for alternative treatment strategies. To discover new(More)
